Abstract
Abstract The present invention provides a multi-axis hand operated controller for a helicopter or other aircraft and includes a generally cylindrical hand grip (2) mounted with its major axis extending generally parallel to the pitch axis of the aircraft when in a neutral position, a forearm rest (3) associated with the hand grip and extending generally parallel to the aircraft roll axis, a first transducer (12) for generating pitch control signals when the hand grip is urged in the aircraft roll axis direction, a second transducer (7) for generating roll control signals when the hand grip is urged to rotate about an axis which is generally parallel to the aircraft roll axis, and a third transducer (10) for generating vertical control signals when the hand grip is urged to rotate about its major axis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A multi-axis hand operted controller for an aircraft including a generally cylindrical hand grip mounted with its major axis extending generally parallel to the pitch axis of the aircraft when in a neutral position, a forearm rest associated with the hand grip and extending generally parallel to the aircraft roll axis, a first transducer for generating pitch control signals when the hand grip is urged in the aircraft roll axis direction a second transducer for generating roll control signals when the hand grip is urged to rotate about an axis which is generally parallel to the aircraft roll axis, and a third transducer for generating vertical control signals when the hand grip is urged to rotate about its major axis.
Claim 2
Dependent Claim
120 words
A multi-axis hand operted controller for an aircraft including a generally cylindrical hand grip mounted with its major axis extending generally parallel to the pitch axis of the aircraft when in a neutral position, a forearm rest associated with the hand grip and extending generally parallel to the aircraft roll axis, a first transducer for generating pitch control signals when the hand grip is urged in the aircraft roll axis direction a second transducer for generating roll control signals when the hand grip is urged to rotate about an axis which is generally parallel to the aircraft roll axis, and a third transducer for generating vertical control signals when the hand grip is urged to rotate about its major axis.
Claim 3
Dependent Claim
13 words
A controller as claimed in claim 1 wherein the transducers comprise force transducers.
Claim 4
Dependent Claim
13 words
A controller as claimed in claim 1 wherein the transducers comprise displacement transducers.
Claim 5
Dependent Claim
17 words
A controller as claimed in claim 2 or claim 3 wherein the transducers generate electrical control signals.
Claim 6
Dependent Claim
17 words
A controller was claimed in claim 2 or claim 3 wherein the transducers generate optical control signals.
Claim 7
Dependent Claim
21 words
A controller as claimed in claim 1 wherein the hand grip is mounted for linear movement along the aircraft roll axis.
Claim 8
Dependent Claim
36 words
A controller as claimed in any of claims 1 to 5 wherein the hand grip is mounted for large diameter arcuate movement which approximates over a small arc to linear movement along the aircraft roll axis.
Claim 9
Dependent Claim
20 words
A controller as claimed in any of the preceeding claims wherein the forearm rest is fixed relative to the aircraft.
Claim 10
Dependent Claim
37 words
A controller as claimed in any of claims 1 to 7 wherein the forearm rest is mounted to slide along the aircraft roll axis to faciliate movement of the hand grip without the introduction of cross coupling.
Claim 11
Dependent Claim
37 words
A controller as claimed in claim 8 or claim 9 wherein the forearm rest has a groove in the upper surface thereof for receiving the forearm and wherein the groove extends parallel to the aircraft roll axis.
Claim 12
Dependent Claim
11 words
A controller substantially as claimed herein with reference to the drawings.
